BOlLER-BRACE.

SPECIFICATION forming part Of Letters Patent No. 605,432, dated June '7, I898. Application filed January 21, 1898. Serial Ila/667,480. (No model.)

To ctZZ whom it may concern.-

Be it known that I, ABRAM F. HUSTON, a citizen of the United'States, and a resident of Coatesville, Pennsylvania, have invented certain Improvements in Boiler-Braces, of which the following is a specification.

The object of my invention is to so construct a brace for staying the heads of steamboilers and like structures that they can be made from a single piece of flat iron or steel without Welding and to obtain sufficient strength to withstand pressures without covering so much of the boiler-plate as to render it objectionable on this account, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of myimproved boiler-brace. Fig. 2 is a section on the line 2 2, Fig. 1. Fig.3is a section on the line 3 3, Fig. 1. Fig. 4 is a section on the line 4 4, Fig. 1. Fig. 5 is a section on the line 5 5, Fig. 1; and Fig. 6 is a diagram view showing one blank in full lines and adjoining blanks in dotted lines.

Referring in the first instance to the diagram Fig. 6, a sheet of metal of the proper Width is punched at intervals, forming a series of holes a, those at one side of the sheet alternating with those of the other side. These holes are punched at a given distance from each edge of the plate, and the plates are cut from each hole to the edge on the line a, forming one head B of the blank A. The plates are severed on the line a from the holes a a.

on one side of the plate to the hole a on the opposite side, thus forming a tapered blank,

the end B of which forms the opposite head is to form the brace from the blank by striking it up in a suitable press, making the body portion 6 U-shapedand'flaredat b, where it joins the head B, and the head B is so shaped as to be at an angle to the body of the brace,

as indicated in Fig. 1." The head B is so pressed as to form flanges d d at each side. These flanges preferably extend up on each side of the body portion 0 of the brace, and the body of the brace from the flanges to the a U shaped section is preferably flat, although in some instances the U-shaped section may extend down to the flanges d 62. Holes 6 e are punched in" the head B and holes e are punched in the head B.

By flanging the head B, I am enabled to considerably increase the strength of the head at the points Where the rivet or bolt holes are punched. At the same timeIdo not cover more of the shell of the boiler than is absolutely necessary, thus preventing injury to the boiler at the rivets.

The boiler-brace maybe struck up in one operation or in a series of operations Without departing from my invention, and instead of the head being flat and the flanges slightly inclined theflanges may be pressed up at right angles to the head or the head and flanges may be curved Without departing from my invention.

I claim as my invention- 1. A boiler-brace made of sheet metal and having a flat head at one end and a head at the opposite end having flanges on each side thereof, said heads being connected together by a body-section, substantially as described.

2. A boiler-brace having a U -shaped bodysection, a flat head at one end of the body-section and at an angle thereto, and a head at 85 the opposite end having flanges at each. side, substantially as described.

3. A boiler-brace having a body portion and two heads, one head being flat and at an angle to the body portion, the-other head having flanges at each side, said flanges extending along apartof the body portion, said body portion being U-shaped at the opposite end, substantially as described.

In testimony whereof I have signed my 5 name to this specification in the presence of two subscribing witnesses.

ABRAM F. I-IUSTON.
